HVM200 Reference Manual Integration Weighting Limits A-23
A.9 Integration Weighting Limits
All data presented is with a reference sensitivity of 1 mV/m/s
2
. The amplitude values on the tables and fig-
ures scale according to the ratio of selected sensor sensitivity values to 1 mV/m/s
2
.
For the following charts, the valid measurement range for each weighting is shown between the noise floor
and the maximum.
